Description

A kind of LED module of glass and lens double protection

Technical field

The utility model relates to technical field of LED illumination.

Background technique

Water and dust in daylight, environment can cause aging and corrosion to lens.Light efficiency is to measure LED product performance simultaneously With the important indicator of quality, traditional LED lamp selects PC or PMMA lens.But these lens are easy by daylight, environment Water and dust are put into corrosion, the phenomenon that aging jaundice, and easily dust stratification dirt occur, are not easily cleaned, so as to cause under light transmittance straight line Drop, keeps illuminating effect uneven, influences the using effect of lamps and lanterns.

Utility model content

To solve drawbacks described above, the purpose of this utility model be to provide it is a kind of it is reasonable in design, light transmittance is high, shines Obvious results fruit is good, good heat dissipation effect LED module.

To achieve the above object, the utility model is achieved through the following technical solutions: a kind of glass and lens double protection LED module, including glass, lens, LED lamp panel, the metal heat sink set gradually from top to bottom, the glass and lens it Between, it is Nian Jie by sealant sealing between lens and radiator, the glass is equipped with glue feeding opening, venthole, the lens and Transparent silica gel is filled between glass, the glass surface is coated with photocatalyst coating.

Further, heat-conducting silicone grease is coated in the LED light back.

It further, further include power supply line, the power supply line passes through metal heat sink by waterproof connector and connects LED board.

Further, LED light emitting source is pasted on the LED board.

Further, the lens are PC lens or PMMA lens.

It is protected the utility model has the beneficial effects that being increased in the top of lens with transparent glass, reduces daylight, water in environment The aging and corrosion to lens such as part and dust, improves the luminescence maintenance rate of mould group.It is touched by the light coated in glass surface Matchmaker's coating makes to be adhered and be decomposed under the action of organic dust of glass surface is in the light that daylight and LED are issued, makes mould Group has certain self-cleaning action, and promotes luminescence maintenance rate.It is packed into transparent silica gel between lens and glass, reduces light Decaying, improve the light extraction efficiency of mould group.

Detailed description of the invention

Fig. 1 is the decomposition texture schematic diagram of the utility model.

Fig. 2 is the overall structure diagram of the utility model.

Wherein: 1, glass, 2, sealant, 3, lens, 4, LED lamp panel, 5, metal heat sink, 6, waterproof connector, 7, power supply Line, 8, glue feeding opening, 9, venthole.

Specific embodiment

The embodiments of the present invention are described further with reference to the accompanying drawing:

As shown in Fig. 1~2, a kind of LED module of glass 1 and 3 double protection of lens, including what is set gradually from top to bottom Glass 1, lens 3, LED lamp panel 4, metal heat sink 5.Pass through between glass 1 and lens 3, between lens 3 and metal heat sink 5 2 adhering and sealing of sealant makes the degree of protection of sealing reach the level of IP65-IP68.Glass 1 is equipped with glue feeding opening 8, outlet Hole 9 is filled with transparent silica gel between lens 3 and glass 1.1 surface of glass is coated with photocatalyst coating, makes to be adhered in 1 table of glass Organic dust in face is decomposed under the action of the light that daylight and LED are issued, and mould group is made to have certain self-cleaning action, Improve luminescence maintenance rate.The LED heat generated is scattered in air by metal heat sink 5 by convection current and radiation.Pass through glass Glue feeding opening 8 on glass 1 can reduce light by lens 3 and glass 1 to transparent silica gel, silica gel is filled between lens 3 and glass 1 Between air when the decaying that generates, improve the light extraction efficiency of mould group.When filling gel, the gas between lens 3 and glass 1 is logical The discharge of venthole 9 is crossed, keep the light transmission of transparent silica gel consistent and is stablized.

In the utility model, it is coated with heat-conducting silicone grease on 4 back side of LED lamp panel, increases between LED lamp panel and metal heat sink 5 The capacity of heat transmission.Power supply line 7 is that the LED lamp panel 4 in mould group provides electric energy, and power supply line 7 is dissipated by waterproof connector 6 across metal Hot device 5 connects LED lamp panel 4, and it is horizontal that the IP grade between metal heat sink 5 and power supply line 7 is reached IP65-IP68.LED It is pasted with LED light emitting source on lamp plate 4, plays conductive, thermally conductive, luminous function.Lens 3 be PC lens or PMMA lens, The top of lens 3 is increased with glass 1 to be protected, and is reduced the aging and corrosion of daylight, the water in environment and dust to lens 3, is promoted The luminescence maintenance rate of mould group.
