Abstract

The utility model discloses an LED bulb capable of dissipating heat and long in service life. The LED bulb comprises a glass bulb, a lamp bead, a middle plate, an aluminum shell, a power supply, a rear cover and a lamp cap, wherein the glass bulb, the lamp bead, the middle plate, the aluminum shell, the power supply, the rear cover and the lamp cap are sequentially connected. The aluminum shell comprises a hollow cone-shaped body and heat dissipation fins. The heat dissipation fins are divergently distributed on the inner wall of the cone-shaped body with the center line of the cone-shaped body as the center of a circle. Gaps are formed between every two adjacent heat dissipation fins. A ventilation port communicated with the gaps is formed in the outer wall of the cone-shaped body. The heat dissipation fins are fixed to the inner wall of the cone-shaped body, the ventilation port communicated with the gaps of the heat dissipation fins is formed in the outer wall of the cone-shaped body, heat is dissipated to the external environment through the ventilation port, the lamp bead is prevented from being too hot to be damaged, and the service life of the LED blub is prolonged. Compared with the prior art, the LED bulb has the higher heat dissipation effect and is more stably used.

Description

A kind of long-life LED bulb lamp of easy heat radiation

[technical field]

The utility model relates to technical field of lighting fixtures, particularly a kind of long-life LED bulb lamp of easy heat radiation.

[background technology]

At present, realizing carbon reduction, green illumination cry surging period, incandescent lamp is eliminated just gradually, the substitute is the novel green lighting source taking LED bulb lamp as representative.

The LED bulb lamp of prior art generally comprises the glass envelope connecting successively, lamp pearl, middle plate, aluminum hull, power supply, bonnet and lamp holder, described lamp pearl is arranged in glass envelope, glass envelope and lamp pearl are fixed on the top of middle plate, power supply is arranged in the inner chamber of bonnet, in order to ensure radiating effect good in LED bulb lamp, conventionally in bonnet, add radiator, but radiating effect is poor, LED bulb lamp is very easily damaged, the illumination life-span is shorter, for the radiating effect having reached, often adopt the mode that strengthens radiator surface area, but the weight that the consequence of doing is like this radiator increases, also improved production cost.

[utility model content]

The purpose of this utility model solves the problems of the prior art exactly, proposes a kind of long-life LED bulb lamp of easy heat radiation, can improve heat dispersion, increases the service life.

For achieving the above object, the utility model proposes a kind of long-life LED bulb lamp of easy heat radiation, comprise the glass envelope connecting successively, lamp pearl, middle plate, aluminum hull, power supply, bonnet and lamp holder, described lamp pearl is arranged in glass envelope, glass envelope and lamp pearl are fixed on the top of middle plate, power supply is arranged in the inner chamber of bonnet, described aluminum hull comprises bullet and the radiating fin of hollow, described radiating fin is taking the center line of bullet as the center of circle on the inwall that divergent shape is distributed in bullet, between adjacent two radiating fins, be provided with gap, on the outer wall of described bullet, offer the ventilating opening being connected with described gap, radiating fin forms a columniform cavity in bullet, one end of described bonnet embeds and is fixed in cavity.

As preferably, described middle plate is cone shape, and middle plate bottom is provided with deck, and described middle plate connects and fixes through deck and aluminum hull, on the outer wall of middle plate, offers thermovent, and described thermovent passes middle plate and arrives the bottom of deck.

As preferably, described thermovent is communicated with gap.

As preferably, described bonnet and lamp holder are spirally connected fixing.

As preferably, described lamp holder is bolt connection type or buckled lamp holder.

The beneficial effects of the utility model: the utility model is by being fixed on radiating fin on the inwall of bullet, on the outer wall of bullet, offer the ventilating opening being connected with the gap of radiating fin, the heat of ventilating mouthful by dissipation of heat in external environment condition, extend prevent lamp pearl because of excess Temperature cause damage, extend service life of the present utility model, compared with prior art, the utility model radiating effect is stronger, uses more stable.

Feature of the present utility model and advantage will be elaborated by reference to the accompanying drawings by embodiment.
