Abstract

The utility model provides long afterglow lamp, comprising a lamp body. The long afterglow lamp is characterized in that the lamp body is sheathed in a light transmitting long afterglow fluorescent rubber sleeve. The utility model has simple structure and simplified manufacturing process; the long afterglow fluorescent powder in the long afterglow fluorescent rubber sleeve can absorb the ultraviolet or the visible light from the light source of the lamp body, and accordingly, when the lamp body is turned off, the long afterglow fluorescent powder in the long afterglow fluorescent rubber sleeve also can light for some time, and can play roles in illuminating or indicating continuously.

Description

A kind of Long afterglow lamp

Technical field

The utility model relates to a kind of illuminator lamp with long-afterglow fluorescent characteristic, specifically a kind of Long afterglow lamp that still can continue luminous a period of time behind power cutoff.

Technical background

Along with the development of technology, the performance of compact fluorescent lamp can satisfy the needs of illumination, and is applied to various occasions.Long after glow luminous material is used widely in indicative occasion, comprises fields such as fire-fighting, boats and ships, building, traffic, railway, military affairs.

In fire-fighting domain, when emergency, power interruptions took place, escape indication energy channeling direction made people can debate other direction when critical.But have only the direction indication not enough in occasions such as the stair of building, underground, inner corridors, these places almost do not have natural daylight, and illuminating effect too official post people can't be seen the road of underfooting clearly, causes confusion easily.The lamp that objectively needs to be used to throw light on still can play certain illuminating effect after power interruptions.Illuminator lamp with long afterglow property designs for addressing that need.

The common manufacture method of fluorescent lamp that has long afterglow property at present is: when making fluorescent tube, earlier long after glow luminous material is coated in the glass tube before being coated with fluorescent material.Because long after glow luminous material is coated in the inside of glass tube, complex process, thickness, the uniformity of coating are had relatively high expectations; Purity requirement to long after glow luminous material is also higher, because impurity will influence the work of fluorescent tube.The fluorescent lamp cost that has long afterglow property with this scheme manufacturing is higher.

Summary of the invention

For overcoming the shortcoming of existing long afterglow property illuminator lamp, the purpose of this utility model provides a kind of Long afterglow lamp, and it does not need special fluorescent tube, and structure, technology are simple.

The purpose of this utility model is achieved in that a kind of Long afterglow lamp, comprises the body of lamp, it is characterized in that: the long-afterglow fluorescent gum cover of outer socket one printing opacity of the body of described Long afterglow lamp, the external diameter of its internal diameter and institute's socket lamp body is complementary.

The shape of the shape of described long-afterglow fluorescent gum cover and institute's socket lamp body is complementary.

Described long-afterglow fluorescent gum cover is made moulding by long lad phosphor is added in proportion in the rubber.

Long afterglow property of the present utility model is realized by the one long-afterglow fluorescent gum cover of socket outside the lamp body, it is simple in structure, simplified manufacture craft greatly, cost reduces, when the lamp body was luminous, the long lad phosphor in the long-afterglow fluorescent gum cover absorbed ultraviolet ray or the visible light from lamp body light source; After the lamp body extinguished, the long lad phosphor in the long-afterglow fluorescent gum cover can also be kept luminous more than 10 minutes, and the light that sends is high-visible, played the effect of illumination or indication.

Embodiment

The utility model comprises the lamp body and is socketed on this external long-afterglow fluorescent gum cover of lamp.The long-afterglow fluorescent gum cover is a printing opacity, and its shape is complementary with the lamp body applied mechanically, and is promptly identical or approximate, and its internal diameter mates with the external diameter of overlap lamp body, be slightly larger than or be equal to or slightly less than overlap the external diameter of lamp body.Wherein an end of gum cover can seal, and also can be two end open types.

The long-afterglow fluorescent gum cover of Long afterglow lamp is to add in the rubber by long lad phosphor is concerned by a certain percentage, thereby makes the rubber sleeve of required form and size.Long lad phosphor in the long-afterglow fluorescent gum cover absorbs ultraviolet ray or the visible light from lamp body light source, and after the lamp body extinguished, the long lad phosphor in the long-afterglow fluorescent gum cover can also luminous a period of time.The preferred silica gel of described rubber sleeve material.Long lad phosphor is selected the inferior plumbous type light-accumulating luminescent material of sulfuric acid for use or selected for use with the aluminium oxide is the light-accumulating luminescent material of main component.According to the needed twilight sunset illumination of actual conditions, the selected required long lad phosphor deal of unit are, then according to the thickness of silica gel sheath, the weight ratio of selected long lad phosphor and silica gel.For reaching effect preferably, the weight ratio of long lad phosphor and long-afterglow fluorescent gum cover is chosen between 1% to 25%, and the thickness of long-afterglow fluorescent gum cover is selected between the 0.1mm to 3mm.After the lamp body extinguished, twilight sunset was kept characteristic as shown in Figure 1, and fluorescence can be kept more than 10 minutes clearly.

Embodiment one

Shown in Fig. 2 a-c, present embodiment adopts the lamp body 2 of cover type, so the also approximate cover type of the shape of long-afterglow fluorescent gum cover 1 (is seen Fig. 2 a), is socketed on lamp body 2 appearances (as Fig. 2 b, 2c), can obtain a cover type Long afterglow lamp.

Embodiment two

Shown in Fig. 3 a-c, the lamp body 3 that present embodiment adopts is the two lamp tube structures (seeing Fig. 3 b) of compact.Long-afterglow fluorescent gum cover 1 one ends are sealing, and an end is placed in the outside of 3 pairs of fluorescent tubes of lamp body for opening wide, and 3 pairs of lamp tube covers of whole lamp body is gone into (see Fig. 3 a, 3c) in long-afterglow fluorescent gum cover 1, can obtain the two lamp tube structure Long afterglow lamps of a compact.

Embodiment three

Shown in Fig. 4 a-c, the lamp body 4 of present embodiment is a straight pipe type, and long-afterglow fluorescent gum cover 1 is a hollow tubular, and two ends are uncovered (seeing Fig. 4 a), be enclosed within straight pipe type lamp body 4 appearances, promptly become the Long afterglow lamp of straight pipe type.

The utility model Long afterglow lamp contour structures is not limited to above-mentioned specific embodiment; cooperate all kinds of lamp bodies different external form and structure; the Long afterglow lamp gum cover can also have more profile, size and more aggregate erection mode, and the Long afterglow lamp that forms according to above-mentioned thought design all belongs to the protection range of this patent in every case.
